Ah, now we come to the essential point of disagreement. I don't really want "my" government interacting with employees or customers based on anything other than mutually voluntary association. The opportunity for abuse is too great.
No, the opportunity for abuse is too great if the door is left open to pure at-will government employment for all employees. We've seen it. What you suggesting is that the government should choose winners and losers among religions or political parties and reward those who feel the same way accordingly. That is what is morally reprehensible about the position. The people making the choices of winners or losers aren't owners, stockholders, investors or have any interest in the enterprise. The abstraction known as "the people" own the enterprise. The same "the people" in whose name the Constitution was formed and who applied that Constitution to restrain government from making such choices. The Constitution is, or should be, the overarching "policy" or "manual" of government operation.
